basically my son has asked me, cause he has a question on it in his school work from college, and i cant think of an advantage of having TNC-S over TNS

I am not to sure of the advantage of having a TNC-S system over a TNS, i know that the impedance on the TNC-S is higher and you get nusance tripping but what is the advantage of that system over TNS???????? :S
